Abstract
SISTEMA DE MONITORAçãO DE TEMPERATURA PARA TRANSFORMADORES DE POTêNCIA IMERSOS EM óLEO. Se aplica preferencialmente a transformadores imersos em óleo e apresenta diversas facilidades no sentido de tornar o monítoramento de temperatura mais confiável e seguro, com destaque para a para medição redundante de temperatura do topo do óleo, autocalibração das entradas de medição de temperatura por meio de referências internas e circuitos eletrónicos especifícos, temporízação entre a ativação sucessiva dos grupos de resfriamento forçado quando da desatívação do sistema de monítoração em tela, relógios internos com alimentação auxiliar sem bateria, segurança reforçada na sinalização de alarmes por temperatura elevada e finalmente ajuste automático dos valores de alarme do diferencial de temperatura do Comutador de Derivações em Carga.
